Which QSAR descriptors are related to ligand entropy?

I am trying to create a ML model which includes various energy terms accounting mainly for the enthalpic contribution to ligand-binding. However, entropic contribution is neglected, although it...

Best protein-ligand sets for docking from DUD-E database?

I am testing a new scoring function for docking and I am looking for simple protein-ligand data sets from DUD-E (only!) in which the binding cavity is well defined and not very flexible. As such,...

Minimum protein-ligand binding affinity difference to claim that a ligand is stronger binder ?

I have a ligand with binding affinity (Kd, Ki, IC50, EC50) measured by a protein-ligand binding in vitro assay. We don't know the experimental error of the measurements. In you experience, how...

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.
